Hi All,

I was hoping someone could give me some troubleshooting thoughts on an issue I’m having with my outdoor speakers (Polk Atrium 6) connected to my Sonos Amp (Gen 2). 

I have 4 Polk Atrium 6 speakers (2 pairs) connected to my Sonos Amp. One pair on my upper patio and one pair on my lower patio.  I also have volume control knobs on the inside of my house for each pair.

I’ve had this setup for 6 years with no issues.

Last week, one of the upper patio speakers stopped working. The other upper patio speaker worked and so did the lower patio speakers.  I thought the one speaker may have went, so I bought a new pair of the same exact speakers.  They came today - I unplugged the amp, disconnected the non-working speaker/reconnected the new speaker, plugged the amp back in.  Thought this would be a simple fix - of course not.  
 

Now both upper patio speakers are not working.  The lower patio speakers still work.  I double checked that I hooked up the new speaker correctly and tried resetting the amp and setting it up again.  No luck, same issue.  The wires on the speaker, that wasn’t working, visually look fine, and the speaker is under the soffit.  
 

Any thoughts what to do next or what might be wrong?  Do I have to replace both speakers on the upper patio (I didn’t think so since same brand/model).  Thanks a lot.
